Ash's Rotom Phone, Ash and others in “Big Brother to the Rescue!”

A battle has been scheduled. Your entrance battle will be against Raihan, who is ranked 8th of the Masters Eight.

Raihan, huh?

What do you mean entrance battle?

If Ash wins, he will exchange ranks with his opponent and be officially confirmed as the 8th ranked member of the Masters Eight who are the strongest trainers in the World Coronation Series. [Be warned, Ash. Once all entrance battles are finished, the final Masters Eight members are decided. This means that other trainers will have to wait until the next season to try their luck in reaching the Masters Eight again.]
